ALL PHYSICS DOUBTS - POST HERE !!

There is this question in m/j 04 Q11 b, it says 'wat does the scattering of alpha particles show about the atomic structure'?
Help..?

- Most of the atom is empty space
-The mass of the atom is concentrated in the central core of the atom called nucleus
-The nucleus has an overall positive charge

Cool Exam

Harder than Chemistery but still very easy

Show all the formulas you use.

Show ALL workings (you can still get marks for wrong answers)

Be CALM and READ the question.

When writing long answers; GET TO THE POINT !!! BE CONCISE !!!!!

thanks!!

Hey angl, u can only use one NOT gate. So ur diagram is incorrect. You should connect the NOT to the electrical sensor and the AND is correct

Okay and thn wat about the humidity sensor..?leave it like that?
n thx

Can anyone please help me with June 2009. 9 (b)? And also Q 11 (b)? THANKS

I dunno how to prepare to phy, I've done overall almost all papers from 2002 onwards. Should I read the theory or repeat the papers (since I didnt do them all today, did them in 3 or 4 months). A lil advice wud b appreciated!

Anyone??

2a) Much of the energy islost to overcome friction resisting its motion.

[tunnellord]

yea you have to leave it.
if you try the circuit, u will see that it fully complies with what it specified in the question

[mdwael]

can someone draw me the circuit for question 8 (a) in May june 2008 summer paper 3 physics second variant?

hey just wondering.. isnt an image from a mirror the same size as the object?

yes.

[guMnam]

okay guys if speed of a moving object is constant then the acceleration is 0.......i noe i m rite.....but is resultant force and acceleration the same thing
